SPRING SADDLE-POST.

SPECIFICATION formingpart of Letters Patent No. 600,377, dated March. 8,1898. Application led November 28, 1896. Renewed December 13, 1897.Serial No. 661,760. (No model.)

T0 LZZ whom t may concern:

Be it known that I, OSCAR F. REEVES, a citizen of the United States,residing at Saginaw, in the county of Saginaw and State of Michigan,have invented a certain new and useful Spring Saddle-Post for Bicycles;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the'art to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a part of this specification.

My invention is a spring saddle-post for bicycles. Heretofore it hasbeen common in manufacturing springs for bicycle saddleposts to placethe spring below the post or surrounding a stem of the post.

My invention consists of placing a spring within a hollow saddle-post,and properly supported therein, and providing means of adjustmentwhereby the tension of the spring may be varied according to the weightof the rider.

I am not aware that a bicycle saddle-post has been so constructed, andtherefore claim, broadly, any means of placing and securing a springwithin a saddle-post.

My invention also contemplates certain minor novel features ofconstruction, such as the preventing of the rotation of the post and thearrangement of several parts ot' the device, whereby it is made simpler,more durable, and otherwise better adapted for use.

Figure l is a side elevation, in part sectional, of my springsaddle-post. Fig. 2 is a sectional view on line X X of Fig. 1. Fig. 3 isa side view of the lower part of the post. Fig. 4. is the same view ofthe spring-support.

In the drawings, l is the saddle-post, and consists of a long hollowtube having upon the upper part thereof the cross-bar 2, which may beintegral therewith.

l is a vertical slot extending through the post on both sides thereof,and through this slot the pin 5, hereinafter described, passes. The slotis for the purpose of allowing the post to move up and down as thespring is depressed.

3 is thespring-support, fitting in the lower end of the post, and may bea hollow tube, as

4in in the usual manner.

shown. Upon the upper end of this support 3 rests the spring 4., ttingin the post between the spring-support and the upper end of the post.The spring-support 3 has also a vertical slot 3 extending entirelythrough the tube, and through this slot the pin 5 also passes, as shownin Fig. 2.

6 is a casing fitting the outside of the post and shorter than the postand adapted to pass within the socket of a bicycle-frame and be clampedtherein. Passing directly through the casing and secured therein is thepin 5. When the parts l, 3, and 6 are placed in position, the slots land 3 will be in line, and through these slots the pin 5 is passed andsecured in the outside casing 6. will then have a vertical movement inthe post the length of the slot 3', andthe post l will have a movementin the casing the length of the slots l', thus allowing the spring to bedepressed the distance between the top of the pin 5 and the top of theslot l', which is the limit of the movement of the post.

In order that the tension of the spring may be adjusted, I provide ahook 7, engaging the pin 5 inside of the spring-support 3, provided withthe depending threaded end 7', provided with a milled nut 8, which islarger than the tube or support 3, whereby when the nut 8 is turnedupward on the end 7 the tube 3 will be pressed upward in the post 1, thelimit of its movement upward being the length of the slots 3. It willthus be seen that by turning the nut 8 up or down the tension of thespring will be increased or diminished.

9 is a jam-nut below the nut S on the end 7 and holds the spring-support3 in the position in which it may have been adjusted.

When these parts are collected and arranged as described andillustrated, the post is in condition to be attached to a bicycleframe,which is done by taking out the ordinary saddle-post and inserting thispost and casing in place thereof and clamping it there- The height ofthe saddle is adjusted in the same manner as with the ordinarysaddle-post-viz., by clamping the casing 6 in the proper position in thebicycle-frame.

In order to adjust the spring to dierent weights or to take up thetension of the spring, the device must be removed from the frame Thetube 3 IOO and the milled nut 8 turned as described and then replaced inthe frame. l y

Itis evident from the above description of my invention that the same issusceptible of modication in its means of adjustment without materiallydeparting from the principle of my invention, and therefore I do notwish to limit myself tothe exact form and means illustrated anddescribed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. Aspring saddle-post for bicycles, com.` prising a hollow post,aspring 'fitting i-nside the post, a support for the spring in lower endof the post, a casing for thev post fitting the bicycle-frame, a pinpassing through the casing and through slots in the post and lthespring-support, and means as-described for adjusting thespring.

2. A spring saddle-post for bicycles, comprising a hollow saddle-posthaving at its upper end a cross-bar, and in its lower end a tubesupported on a pin passing through slots in the post and tube andsecured in a casing on outside of post, a spring iittin g the hollowpost above the tube and resting upon it, a casing for the post tting thebicycle-frame and'containing the pinpassing through the post, wherebythe post is held from rotation, a hook passing within the tube andengaging the pin, a milled nut on the lower-end of the hook and largerthan the tube, whereby by turning up the nut the tube will be forced upthe hollow post and the tension of the spring thereby varied, asdescribed.

3. In a spring-post for bicycle-saddles, cornprising a hollow postcontaining a spring, the means for supporting and adjusting the springand post, comprising a casing for the 4o the bicycle-frame, and 'themeans for securing it to the frame, of a spring in the hollow post, atube in the lower end of the post abutting the spring and `having twovertical slots inline, a'pin passing through the casing, post, andtubein the slots therein, thereby holding the tube and spring'in thepost, a hook engaging the pin within the tube and having a dependingthreaded -end provided with a milled nut larger than the tube, wherebythe tube and spring may be adjusted, and a jamnut on the end of thehook, as described.

5. In a spring-post for bicycle-saddles, the combination with a hollowsaddle-post and a casing surrounding the hollow saddle-post, of a springin the hollow saddle-post, and apin passing through the casing and .postlbelow the spring through vertical slots in the post, as described. Y

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
